SHEET-METAL WHEEL.

Patented J une 30, 1914.

Application tiled June 15, 1911. Serial No. 633,242.

To all /wlmm it muy concern.:

Be it known that we, Fl-:mx Il. lloRN and ADAM WAGNER, citizens of theUnited State-s. residing at Cedar Falls. in the county of Blackhawk-,andState of Iowa, have invented a new and useful Improvement in Sheet-Metal Wheels, of which the following is a speciieatio n. t

The object of our invention is to provide a sheet metal wheel whichcomprises but few parts, is lightin weight and possesses greatmechanical rigidity.

Referring to the accompanying drawings. Figure 1 is a side view inelevation of a wheel embodying our invention: and Fig. 2 is an enlargedeross-seetional view on line 2-2 of Fig. l.

The wheel of om' invention consists` of two complementary halves orsections indicated as a Whole by A and B whieh. when assembled, meet ina/plane C perpendicular to the axis of the wheel. The sections areformed outotl sheet metal and each com- ,prises a hub portion 1` aplurality of roncave spoke members Q.extending radially from thehubportion and having straight edges-which lie substantially in the meetinglane C. a flat annular portion 25 in whic the outer ends of the spokeinem` bers terminate, and a tread portion 4. 'Ijhe spoke members of thetwo wheel sections converge gradually toward the outer ends toa, point 5from which they etmverge lsuddenly to a meeting point t lying in theeotnmon meeting plane (),l` eourse. it is to be understood that when werefer to the edges of the spoke members as lying in the common meetingplace we do not mean that in the actual eonstruetion ol' the ula-el theparts must tit together as perl'ertly as shown in the drawing. Snell amathemati4 cally perfect tit wouldV not usually be obtained in practice,nor is it nei'essary in the metil-al embodiment of 'the ii'i'ontion. It1s sutlieient that the-'two halves of the wheel come togetherasf-'closely' as the working oll the sheet metal permits. From thepoint, 7 at the outer end of the flat annular portion 3, theI metaldiverges outwardly at H and is then turned inwardly at t) parallel tothe axis ot' the wheel to forln a llat tread rim.

Suitable fastening devices such as rivets lt)- pass through the annularportion Il for rigspokes and the tread rim.

served that' the walls ofthe hub portions 1` are substantially paralleland form a hub ortions are pro The annular' portions 3 are ofconsiderablev width and when brought together form a connection ofdouble thickness between the It will be Yob` chamber H. The hub videdwith'openings ll t rough which ex tends a bushing l2. The hub portionsare eaeh provided with an annulaxreeesys 13" around the hub opening. Inthe hub chainber H is arranged a spacing collar 14 which tits snuglyaround the bushing l2. The ends of the collar ll rest in the recesses 13of the huh portions. Suitable. fastening devices sut-h as rivets lrpassthrough the vhub `portions without engaging the` collar 14 for rigidlyclamping the hub portions against the. eollar. 'lhe fastening devices 15also hold m place the sheet metal caps 16 which il engage the. outerends ofA the bushing 12 to prevent the same from pushing or workingsidewise. The caps lti are'each provided with an opening 17 which isine' 'il-,l :Lline` ment with the bushing l2. The caps 16 are providedwith outer flanges 18 which lie tlat. against the walls of the hub'portions when the wheel is assembled. The above lmb constructionprevents the wheel sections from spreading or getting out of position atthe center, and thus enables the wheel to support a heavy load.

Having thus described our invention` what we elaim as new and desire to-secure by lietters latent ol the llnited lStates is:

l. sheet metal wheel eonsistingof two sections which comprise each a hubportion, spotfl# members and a tread portion. the walls ot' the hubportions heilig substanltially parallel. forming an annular hubehalnlier. the extremities of the parallel walls ol' the lmb portionseach having formed therein an annular recess.- nnl annular spat-ingcollar adapted to rest within said recess. a tvlindrit'al vluishingmounted within said spat-ing collar and extending equi-distant on eat-hside thereof` 'retaining raps resting against the outer extremity ofsaid bushing and 'means l'or securing said retaining raps to the hubportions above said annular eollar. substantially as and l'or thepurpo-e sperilitd.

L. sheet metal wheel ronsisting ol' tuo etunplenu-ntary sertions whicheomprise ,y xo portions a. cylindrica fjaeh ahb portion, is ke membersand a )xed portion, the 'wal of the hub portion -beinl substantiallyarallel to each other K aving n linin s aft openings, 'the saidy"5pa1'allel walls of't e hub portions each havformed therein an annularreess, a cy# lindricalspacing collar ada ted to rest within said recessandadapteJ to lie Hush with the shaft openins'formed in the hub bushingadapted to in said spacing collar and extendrest wit mg equi-distant oneach side thereof, retaining `caps having each an.openii1g. formed 'ftherein adapted to lie in ahnement with the 1,1.o2,1es

ope/ning formed inthe bushin eachof the 1B said caps having a peripheraharige, and.: means extendi through said'fia es and the paralleLwgs ofthe hub mem rs fol connecting the hub portions.. and the caga togetherwhereby the said bushing will. e-20 prevented .from latral movement, AInwitness whereof, we hereunto subscribe our names this 2nd day of June,1911.
